Intel Core i5-14401E vs Intel Core Ultra 5 135HL Comparison

Head-to-Head Benchmarks

The recorded data shows a single-sided benchmark comparison in this matchup. The Intel Core i5-14401E has six Cinebench results across three renderer versions, while the Intel Core Ultra 5 135HL has no recorded benchmark scores in the database. This means every head-to-head comparison must rely on the i5-14401E's absolute scores and its position against other CPUs, since the Ultra 5 135HL lacks any measured performance data.

The i5-14401E delivers a Cinebench R23 multi-core score of 18161 and a single-core score of 2564. In Cinebench R20, it records 7627 multi-core and 1076 single-core. The older Cinebench R15 test shows 1830 multi-core and 258 single-core. These scores place the i5-14401E at the 60th percentile among all CPUs in the database, with an average benchmark score of 5253.

Without any benchmark entries for the Core Ultra 5 135HL, the database cannot establish a direct performance delta between these two processors. The nearest rivals for the i5-14401E provide context for its standing. The Intel Xeon E5-2699A v4 scores 5259 on average, a 0.1% difference from the i5-14401E. The Intel Core i7-11700B averages 5241, which is 0.2% lower. The Intel Core i9-10850K matches that 5240 average, also 0.2% behind. The Intel Core i5-13400T averages 5210, sitting 0.8% lower.

The data indicates the i5-14401E performs within a narrow band around these four rivals. Its multi-core Cinebench R23 result of 18161 suggests strong sustained throughput for a 65W desktop processor, but the absence of Ultra 5 135HL data prevents any direct score-to-score comparison. The percentile ranking of 60 for the i5-14401E versus 50 for the Ultra 5 135HL offers a coarse signal, but the Ultra 5's percentile derives from zero recorded benchmarks, making it a placeholder rather than a measured value.

Architecture Differences

The two processors come from different Intel generations and use different silicon designs. The i5-14401E belongs to the Core 14th Gen series, built on Raptor Lake architecture with the Raptor Lake-R codename. The Core Ultra 5 135HL belongs to the Core Ultra Series 1, using Meteor Lake architecture with the Meteor Lake-PS codename. The process nodes differ: the i5-14401E uses a 10 nm node, while the Core Ultra 5 135HL uses a 7 nm node. Both are fabricated by Intel.

Core counts separate these parts significantly. The i5-14401E has 6 cores and 12 threads, while the Core Ultra 5 135HL has 14 cores and 18 threads. The Ultra 5's core count almost doubles the i5's, but its thread count does not scale proportionally, indicating a heterogeneous core layout typical of Meteor Lake. The i5-14401E uses a conventional symmetric core design with 6 cores and hyper-threading, yielding 12 threads. The Ultra 5's 14 cores produce only 18 threads, suggesting a mix of performance cores with hyper-threading and efficiency cores without it.

Cache hierarchies also differ. The i5-14401E carries 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. The Core Ultra 5 135HL has a larger per-core L1 at 112 KB, a larger per-core L2 at 2 MB, but a smaller shared L3 at 18 MB. The die size for the i5-14401E is recorded at 215 mm², while the Ultra 5 135HL has no die size entry.

Clock speeds show a different tradeoff. The i5-14401E has a base clock of 2.50 GHz and a boost clock of 4.70 GHz. The Core Ultra 5 135HL has a lower base clock of 1.70 GHz and a slightly lower boost clock of 4.60 GHz. The i5-14401E's higher boost clock gives it a frequency advantage in single-threaded bursts, while the Ultra 5's lower base clock likely reflects its efficiency-focused design and higher core count.

Memory support diverges as well. The i5-14401E supports both DDR4 and DDR5 memory, while the Core Ultra 5 135HL supports DDR5 only, with the database noting that support depends on the motherboard. The i5-14401E supports ECC memory, while the Ultra 5 135HL does not. Both use dual-channel memory buses. The Ultra 5 135HL records a memory bandwidth of 89.6 GB/s, while the i5-14401E has no bandwidth figure listed.

PCIe connectivity differs by generation. The i5-14401E provides Gen 5 with 16 lanes (CPU only). The Core Ultra 5 135HL provides Gen 4 with 8 lanes (CPU only). The i5-14401E's newer PCIe generation and double the lane count give it an advantage for expansion and high-throughput devices. The integrated graphics also differ: the i5-14401E uses UHD Graphics 730, while the Core Ultra 5 135HL uses Arc Xe-LPG 128EU, a more capable GPU solution on paper.

Power envelopes and sockets differ. The i5-14401E has a 65W TDP and uses Intel Socket 1700. The Core Ultra 5 135HL has a 45W TDP and uses Intel Socket 1851. The Ultra 5's lower TDP aligns with its lower base clock and higher core count, suggesting a design aimed at power efficiency rather than raw frequency. The release dates place the i5-14401E at 2024-06-30 and the Core Ultra 5 135HL at 2024-04-07, so the Ultra 5 came to market earlier by approximately three months.

Where Each One Wins

The i5-14401E wins in several measurable categories based on the recorded data. It has a higher boost clock at 4.70 GHz versus 4.60 GHz, which benefits tasks that rely on single-threaded speed. It supports both DDR4 and DDR5, giving it flexibility across different motherboard ecosystems. It supports ECC memory, which matters for systems requiring error correction. Its PCIe Gen 5 with 16 lanes provides double the bandwidth generation and lane count of the Ultra 5's Gen 4 with 8 lanes. Its 65W TDP is higher, allowing more sustained power draw for sustained workloads.

The i5-14401E also has a clear advantage in benchmark data availability. Six Cinebench scores exist for it, giving the database a complete picture of its performance. The Core Ultra 5 135HL has zero recorded benchmarks, so its actual performance remains unmeasured. The i5-14401E's 60th percentile ranking versus the Ultra 5's 50th percentile reflects this data asymmetry, though the Ultra 5's percentile cannot be interpreted as a measured performance level.

The Core Ultra 5 135HL wins in core count and thread count. Its 14 cores and 18 threads exceed the i5-14401E's 6 cores and 12 threads. This suggests an advantage in heavily parallel workloads, assuming the software can utilize the efficiency cores effectively. The Ultra 5 also has a lower TDP of 45W, making it the more power-efficient option. Its 7 nm process node is smaller than the i5-14401E's 10 nm node, potentially enabling better transistor density. The Ultra 5's larger per-core L1 and L2 caches may help with data locality in certain workloads. Its Arc Xe-LPG 128EU integrated graphics likely outperform the UHD Graphics 730, though the database does not include graphics benchmarks to confirm this.

The Ultra 5 also records a memory bandwidth figure of 89.6 GB/s, which the i5-14401E lacks in the database. This does not necessarily mean the i5 has lower bandwidth, only that the figure is unrecorded.

The Verdict

The data presents a lopsided comparison due to missing benchmark information. The Intel Core i5-14401E has six recorded Cinebench scores, an average benchmark score of 5253, and a 60th percentile placement. The Intel Core Ultra 5 135HL has no recorded benchmarks, an average score of 0, and a 50th percentile that appears to be a default assignment rather than a measured result.

For users prioritizing measured performance, the i5-14401E is the only option with verified data. Its Cinebench R23 multi-core score of 18161 and single-core score of 2564 provide concrete reference points. Its nearest rivals, the Xeon E5-2699A v4, Core i7-11700B, Core i9-10850K, and Core i5-13400T, all fall within 0.8% of its average score, indicating it sits in a well-established performance tier.

For users prioritizing core count and power efficiency, the Core Ultra 5 135HL offers structural advantages on paper. Its 14 cores and 18 threads could outperform the i5-14401E in multi-threaded scenarios, but the database contains no evidence to confirm this. Its 45W TDP and 7 nm process node suggest a more power-conscious design. Its Arc Xe-LPG 128EU integrated graphics and 89.6 GB/s memory bandwidth are additional recorded advantages.

The absence of Ultra 5 135HL benchmark data means the verdict cannot favor it based on performance. The i5-14401E's measured results give it the only empirical support in this comparison. Users who need ECC memory, DDR4 compatibility, PCIe Gen 5, or a higher boost clock should select the i5-14401E. Users who need more cores, lower power consumption, or a newer socket should consider the Ultra 5 135HL, but without benchmark confirmation of its capabilities.
